A frightening charge in a specific courthouse
If you just learned you are under investigation for wire fraud in California, or you just read an indictment with your name on it, start with two facts. First, the charge is federal, so your case will be heard in a United States district court, not a California state courthouse. Second, California has four of those courts, and the district named in your papers decides where you go, which prosecutors you face, and which local rules apply.
This page is the California companion to our national wire fraud page. The national page walks through the statute, the guideline math, and the defenses in full. This page covers the same charge through a California lens: the four districts, the prosecutors who bring these cases here, and the Ninth Circuit rules that govern trials and appeals in this state. For the map of all four districts and their courthouse cities, start with our California federal courts overview.
Nothing here forecasts your outcome. The penalties discussed below are legal ceilings and advisory ranges. They are not forecasts, and each case turns on its own facts.
Where your case will be heard
Congress drew the map. The statute provides:
"California is divided into four judicial districts to be known as the Northern, Eastern, Central, and Southern Districts of California."
A separate statute gives those courts their power. It provides:
"The district courts of the United States shall have original jurisdiction, exclusive of the courts of the States, of all offenses against the laws of the United States."
That word exclusive carries the whole point. When the charge is wire fraud under federal law, the state courts do not share the case. The prosecution is brought by a United States Attorney's Office, the judge is a federal district judge, and sentencing runs under federal law.
Each district holds court in its own cities. The law states:
"Court for the Northern District shall be held at Eureka, Oakland, San Francisco, and San Jose."
It states for the east:
"Court for the Eastern District shall be held at Bakersfield, Fresno, Redding, and Sacramento."
The Central District is split into divisions. The statute states:
"Court for the Western Division shall be held at Los Angeles."
It states for the southern division of that district:
"Court for the Southern Division shall be held at Santa Ana."
And it states for the south:
"Court for the Southern District shall be held at San Diego."
Find the district named in your papers first, then open that district page. The Central District of California page covers Los Angeles, Riverside, and Santa Ana practice, and the sibling pages cover the Northern, Eastern, and Southern Districts. The districts differ in size, in where court is held, and in daily practice, so the district page matters more than any general description.
Who brings the charge
Each of California's four federal districts has its own United States Attorney's Office, and that office decides whether to charge, what to charge, and how to negotiate. The offices are the United States Attorney's Office for the Central District of California, the Northern District of California, the Eastern District of California, and the Southern District of California. The agents who investigated your case, often the FBI, usually report to the same district where a charge would later be filed. If your contact so far has been with investigators rather than prosecutors, our page on FBI investigations explains what that contact means and how to respond.
Wire fraud cases in California often begin long before any indictment, with subpoenas for bank and email records, search warrants for phones and computers, or a letter or visit telling you that you are a target. Take those early signs seriously. The investigation phase is when the loss figure gets built, and as explained below, the loss figure usually drives the sentence more than any other single fact.
The Ninth Circuit connection
Every California federal district sits in the same appellate circuit. Under federal law California belongs to the Ninth Circuit, so an appeal from a wire fraud conviction in any California courthouse goes to the United States Court of Appeals for the Ninth Circuit. That matters before trial as well as after, because Ninth Circuit law shapes what the jury hears.
In a California wire fraud trial, the judge explains the charge to the jury using the Ninth Circuit's model criminal instruction for wire fraud. That instruction collects how courts state the charge and frames each element the government must prove beyond a reasonable doubt. Points drawn from that instruction in this page are attributed to the Ninth Circuit's model jury instructions. They describe practice in California federal courts, not a nationwide rule, because other circuits phrase their own instructions in their own words.
What the government must prove under 18 U.S.C. § 1343
The wire fraud statute is 18 U.S.C. section 1343. Its central language is:
"Whoever, having devised or intending to devise any scheme or artifice to defraud, or for obtaining money or property by means of false or fraudulent pretenses, representations, or promises, transmits or causes to be transmitted by means of wire, radio, or television communication in interstate or foreign commerce, any writings, signs, signals, pictures, or sounds for the purpose of executing such scheme or artifice, shall be fined under this title or imprisoned not more than 20 years, or both."
Every defense in this area targets one part of that sentence. The government needs a scheme, aimed at money or property through lies, a wire that crossed a state or national border, and a link between that wire and the scheme.
The statute has a second tier for cases tied to a presidentially declared major disaster or emergency, or to an offense that affects a financial institution. That tier raises the ceiling from 20 years to 30 years for each count and allows a fine of up to one million dollars. The mail fraud page quotes the matching enhanced-penalty language, which section 1343 repeats, in full.
The model instruction described above lists four elements. The first is a scheme to defraud. The defendant took part in a plan, or meant to devise one, to obtain money or property by false pretenses or promises. Planning alone qualifies. Prosecutors need not show a finished theft or that you typed the message yourself, because it is enough that you caused a message to go out.
Second, the statements must be material, meaning they could sway someone's choice to part with money or property. The Supreme Court has addressed this requirement, as the mail fraud page explains. Casual talk or exaggerated sales pitches that nobody sensible would act on should fall short, but a false answer on a loan form to a question the lender posed directly will count.
Third, you must have acted with a purpose to defraud, which has two parts. One is deception, such as false statements or other trickery. The other is using that trickery to take money or property from a victim.
Fourth, a wire that crossed state or national lines must have been used, or caused, to advance an essential part of the scheme. A wire counts as caused when you know it will be used in ordinary business or when its use was reasonably foreseeable. This element gives the defense a real opening. The government must show a wire that actually crossed a state or national line and served the scheme. A purely local call fails the test. The instruction also addresses whether you had to foresee that the wire was interstate, and the wire fraud page quotes that language.
Two more rules from the model instruction are often unexpected. The scheme must aim at traditional money or property, and the mail fraud page quotes the instruction's statement on that point. A plan built only on regulatory harm or on control over information, with no money or property as the goal, falls outside what the statute reaches.
The reverse also holds. If you induced a victim to hand over money through a deal built on a lie, you can be convicted even when the victim received something of value and lost nothing net. A fair bargain does not excuse the lie behind it, though a lack of loss can matter at sentencing.
Wire fraud versus mail fraud (18 U.S.C. § 1341)
Mail fraud, at 18 U.S.C. section 1341, is the sibling charge. Its scheme wording is almost identical, and it carries the same two tiers of 20 and 30 years.
The model instruction boils the difference down to one sentence, which the wire fraud page quotes. It turns on the type of communication used.
Which charge appears on the indictment depends on how the communication traveled. Deliveries by the Postal Service or a private interstate carrier point toward mail fraud. Anything sent electronically, such as emails, texts, calls, or transfers, points toward wire fraud. California prosecutors often charge both, or file separate wire fraud counts for each email in a series. If your papers cite section 1341 rather than 1343, read the mail fraud page, since the defenses and sentencing math carry over largely intact.
The penalties on paper
Treat these figures as upper limits rather than expected results. Nobody can forecast a sentence, since loss, the number of victims, prior record, and the judge's view all affect it.
Prison. Each count carries a ceiling of 20 years, or 30 years if a financial institution is affected or covered disaster funds are involved. Counts stack, so ten charged emails can mean ten separate ceilings, which is why long indictments look so frightening at first. This statute sets no mandatory minimum prison term.
Fines. A felony conviction can bring a general federal fine. An individual can be fined as much as 250,000 dollars, and an organization as much as 500,000 dollars. A separate measure based on the gain or the loss can exceed those figures in a large case, and the bank and disaster tier of wire fraud allows a fine of up to one million dollars. The mail fraud page quotes the fine statute.
Supervised release. Ordinary wire fraud carries a 20-year ceiling and counts as a Class C felony, and supervised release for that class can last up to three years. Supervision starts after release from prison, and breaking its conditions can put you back in front of a judge. The mail fraud page quotes the classification and release statutes.
Restitution. Repayment is often the heaviest part of a fraud sentence. Under the Mandatory Victims Restitution Act, wire fraud falls within the covered offenses, so a conviction commonly brings an order to repay victims in full, in addition to any prison term or fine. The statutory text is quoted on the mail fraud page.
How the sentencing guidelines work
Federal judges use the United States Sentencing Guidelines to set a starting range. For wire fraud, the main guideline is section 2B1.1, which covers fraud and theft generally. Our federal sentencing page explains how judges use the range, and the wire fraud page has a fuller walk-through of the math. Neither replaces advice about a real case.
Section 2B1.1(a)(1) sets the base offense level at 7 for any crime with a ceiling of 20 years or more, and wire fraud qualifies. From there, the loss figure moves the number most.
The guideline counts whichever is larger, the money actually lost or the money you meant to take. Its exact definitions appear on the wire fraud page. Intended loss counts even when the harm was impossible, as in a sting with no real victim. So a failed scheme can be sentenced much like a successful one.
The loss table at section 2B1.1(b)(1) adds offense levels as the dollar amount grows. Losses of 6,500 dollars or less add nothing. At 150,000 dollars the table adds 10 levels, and at 1,500,000 it adds 16. The highest step, 30 added levels, applies to losses over 550,000,000 dollars. These are the current Manual's figures. For sentencings on or after November 1, 2026, Amendment 2 of the Sentencing Commission's 2026 amendments raises them, unless Congress acts: losses of 9,000 dollars or less add nothing, the 10-level step moves to 200,000 dollars, the 16-level step to 2,000,000, and the 30-level step to 750,000,000. Because the loss figure often moves the range more than anything else, disputes over that number are frequently central to the case.
Section 2B1.1(b)(2) adds levels for victim-related factors. Two levels apply if there were ten or more victims, if mass marketing was used, or if even one victim suffered substantial hardship. Substantial hardship to five or more victims is worth 4 levels, and to 25 or more is worth 6. Only the largest of these increases is used.
Further increases cover sophisticated conduct. Section 2B1.1(b)(10) adds 2 levels for moving a scheme to avoid law enforcement, running a large share of it from abroad, or using sophisticated means on purpose, and it sets a minimum result of level 12. Schemes involving stolen identities, access devices, or authentication features can draw more under section 2B1.1(b)(11). Position-of-trust and leadership adjustments from other guideline chapters may also apply where the facts fit.
The criminal history category and the offense level meet on the sentencing table, which yields a range in months. That range is advice to the judge, not a command, and the statutory ceiling limits any sentence.
Defenses that actually arise
Each defense below grows out of one of the elements above. None guarantees a result. They depend on the facts, the documents, and the law of the Ninth Circuit.
Lack of fraudulent intent. Prosecutors must prove what you were thinking. Evidence that you honestly believed your statements, dealt openly, relied on professional advice, or ran a business that failed for ordinary reasons can undercut intent. A failed startup is not automatically a fraud. The central question is whether you knew the claims were false and meant to use them to get money.
Immaterial statements. If the claimed lies could not have swayed anyone's decision about money, the materiality element is missing. Opinions, vague optimism, and remarks nobody would reasonably rely on fit here.
Challenge the wire. Federal jurisdiction depends on an interstate wire. A lawyer checks each charged email, call, and transfer: when it was sent, how far it went, and whether it advanced the scheme or only came after. A message that stayed within one state, or one sent after the scheme was already complete and that served no further purpose, may not support its count. In California this argument draws on the model instruction, which requires a real interstate wire.
No money or property as the goal. If the goal was only to gain a regulatory edge, embarrass a rival, or exercise control, and no traditional property was sought, the charge reaches further than the statute does. The model instruction speaks to this point, and the mail fraud page quotes it.
Repayment and good faith. Running a genuine business does not protect you if the government says particular statements used to obtain money were knowingly false. The model instruction addresses an intent to repay, and the wire fraud page quotes it. Repaying victims can help at sentencing, because a lower actual loss may reduce the guideline range, though it does not make the charge go away.
The small-case policy. The Justice Department has a prosecution policy about minor private disputes. If your facts fit it, your lawyer can bring it to the prosecutors at the relevant United States Attorney's Office early on. The mail fraud page quotes the policy in full.
First steps to take
If agents have approached you, you received a target letter or a subpoena, or coworkers are being contacted, do three things first. Do not discuss the facts with agents, coworkers, or in writing, because any explanation can later be used to show intent. Keep everything, since deleting emails, messages, or files can create an obstruction problem worse than the fraud charge. Then hire a federal criminal defense lawyer before you sit down with anyone from the government, including for a proffer. Early help can sometimes narrow an investigation and set terms for any contact.
Once charges are filed, the advice holds and the urgency grows. Review the indictment with your lawyer, looking at each count and each charged wire. Confirm which district brought the case and where the court sits, since it affects how far you travel, when things happen, and which local rules apply. Learn what loss figure the government is using and how it reached it, and ask how the range shifts if that figure changes. In most wire fraud cases, the dispute over loss is the sentencing dispute.
A final reminder: this page lays out legal ceilings and guideline ranges. It cannot tell you what any person will receive. Judges consider the guidelines, the person's background, and what actually happened, and the sentence that counts is the one a judge imposes in an actual courtroom.
